Data types in PLC Designer

526 DMS 3.2 EN 02/2011 TD29 

11.2.5 Structures

Structures are created as objects in the Object Organizer under the register card

Data types. They begin with the keywords TYPE and STRUCT and end with

END_STRUCT and END_TYPE.

The syntax for structure declarations is as follows:

TYPE <Structurename>:

<Structurename> is a type that is recognized throughout the project and can be used

like a standard data type.

Interlocking structures are allowed. The only restriction is that variables may not be

placed at addresses (the AT declaration is not allowed!).

Example for a structure definition named Polygonline:

TYPE Polygonline:

Start:ARRAY [1..2] OF INT;

Point1:ARRAY [1..2] OF INT;

Point2:ARRAY [1..2] OF INT;

Point3:ARRAY [1..2] OF INT;

Point4:ARRAY [1..2] OF INT;

End:ARRAY [1..2] OF INT;
